Meh...I rented LA Noire from Gamefly. Finished it with 25 hours of gameplay. Its highly overrated. Same shit over and over. The story and graphics are amazing, but the shallow gameplay really takes away from the potential of this game. I had fun, I finished it, but I will not pay for any DLC.
7.5/10 at most. The 9/10 ratings are ridiculous. People have been sheppified into "OMG Facial motion capturezor". If you like doing the same thing over and over 21 times for cases and 40 times for street crimes, then by all means, give it a 9.
